4 Claims. (Cl. 30020) This invention relates to apparatus for fillingbrush handles and is directed more particularly to improvements inapparatus for presenting successive handles to means for injectingadhesive into the brush receiving holes thereof.

The principal object of the invention is directed to the provision ofnovel apparatus for releasably holding and transporting successive brushhandles for the injection of cement or adhesive into the holes thereofand into which the brush elements are inserted.

According to the invention the apparatus is constructed and arranged sothat handles are inserted therein and are transported thereby to thecement injecting means after which the brush elements may be inserted inthe holes. The handles are transported in a step by step manner, thebrush elements are inserted and the brushes ejected from the machine.

Brushes of the type referred to include a handle having a hole in theend thereof and a bristle carrier of wire or the like is insertedHeretofore the handle holes have been filled with cement while held inthe hand and the bristle carriers are thereafter inserted but such aprocedure entails time and labor which contributes to high costproduction.

According to this invention, the handles are placed in the machine sothat they progress to a station where the cement is injected into theholes thereof and while in the machine the bristle elements may beinserted and subsequently the brushes are automatically ejected.

With the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction and in the combination and arrangement of parts as will.be hereinafter more particularly pointed out in the claims hereuntoannexed and more fully described and referred to in connection with theaccompanying drawings wherein:

Fig. l is a side elevational view of apparatus for filling brush handlesembodying the novel features of the invention;

Fig. 2 is a partial plan view of the transporter of the apparatus shownin Fig. 1;

Figs. 3 and i are plan and front elevational views respectively of oneof the handle pocket mechanisms of the apparatus;

Fig. 5 is a sectional elevational view through one of the handlesupports of the transporter;

supported by a support and. engaged in one of the pockets of thetransporter.

Referring now to the drawings more in detail, the invention will befully described.

Horizontal and vertical members 2, 4 and 6 are secured together toprovide a frame for the apparatus which may be in any desired form.

A receptacle 8 is supported by members such as It at the upper side ofthe machine; Said receptacle is adapted to contain cement or adhesive ofthe desired type and has a depending discharge conduit i2 provided witha nozzle M. A valve mechanism indicated by I6 is operable by areciprocable member l8 so as to discharge a predetermined quantity ofcement or adhesive on each reciprocation of the member [8 to the left.

A bearing standard 20 extends upwardly, as shown, and has a shaft 22rotatable thereinto, the upper end of which is fixed to a transporter 24which in the form of the invention shown is a circular disc.

A motor 30 fixed to a plate 32 which is secured to the frame, as shown,has a drive pulley 34 on its shaft 36 which is connected by a belt 36 toa pulley 38 fixed on a shaft 40. Said shaft A l is rotatable in abearing 42 and has a sprocket 44 connected by a chain 46 to a sprocket48 fixed on a shaft 50.

The shaft 58 is rotatable in a bearing 52 and has fixed on its lower enda driver 54 for operating a Geneva gear kit which is fixed to shaft 22.

The Geneva gear and driver therefor will be constructed, as the shaft 56is continuously rotated, to rotate the shaft 22 in a step by step mannerso as to present the pockets, carried by the transporter and to bedescribed, successively to the nozzle l 4.

In the form of the invention shown, there are sixteen pockets associatedwith the transporter wherefor the Geneva gear and driver therefor willbe of well known form to rotate shaft 22 intermittently through an angleof twenty-two and one-half degrees.

The pockets are indicated in a general way by 60 and are shown more indetail in Figs. 3 and 4.

Brackets 62 are secured to the transporter 24 by screws 64 and haveposts 66 extending upwardly therefrom. Jaws 68 are pivoted on the postsand are formed to relatively diverge at their inner or rear ends it.Ears l2 extend from the brackets 62 and screw members "M are providedaround which are compression springs [6 disposed between the ears l2 andjaw ends Hi. The said ends 1i) loosely receive the screw members 14 sothat the springs tend to separate said ends 3 and yleldingly hold theouter ends of the jaw members in closed relation. Nuts 18 in engagementwith the screw members 14 limit movements of the jaw ends Ill.

The portions of the jaw members outwardly of their pivotal connectionswith the brackets 62 extend relatively outwardly and inwardly at l8 andB to provide pockets 82 therebetween. The extremities 84 of the jawmembers extend in a diverging relation.

The jaw members are yieldingly separable so that the upper end of abrush handle may be passed between the diverging end portions thereofinto the pockets therebetween to be releasably held therein. The handlesmay be pulled outwardly from pockets since the jaw members areyieldingly separable.

A ring-like plate 86 is provided below the transporter 24 which hasfixed thereto a plurality of hubs 88 which are in sliding engagementwith rods 90 fixed to and depending from transporter 24.

Handle supports 92 are fixed to the upper side of the plate 86 and havedepressions 94 in the upper sides thereof. Openings 96 extend throughthe supports 92 and plate.

The plate 86 is movable up and down on the rods 99 so that the lower endof a brush handle may rest in the depression of the support and besupported thereby in such a manner that the upper end of the handle ispositioned in the pocket thereabove, as shown in Fig. 6. The plate 86 ismovable up and down to accommodate brushes of different lengths and setscrews 85 engage the rods 90 to hold the plate in adjusted positions.

In operation the transporter is moved clockwise in a step-by-step mannerand brush handles are inserted in those pockets 6B which are advancingtowards the nozzle Hi. The handles are inserted into the pockets byresting the lower ends thereof in the supports 92 and swinging theirupper ends inwardly between the diverging ends of the jaws and into thepockets 82.

As each brush handle arrives to a position below the nozzle I4 cement isdischarged into the hole h of the handle and as the handles move awayfrom the nozzle the brush elements are inserted in the said holes.

The handles may be manually removed from the transporter but an ejector98 is provided therefor on the upper end of a support ltd which issecured to the frame. This ejector is arranged to be engaged by theupper end of the brush handles with a cam action so as to cam and ejectthe handles as the transporter moves them clockwise and into engagementtherewith.

In the event a brush handle projects upwardly from a pocket as itadvances towards the nozzle the motor is cut out to stop the machine bya switch H12 having an operating lever I04 disposed in the path ofmovement of an advancing brush.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claims rather than by theforegoing description, and all modifioations and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaims are therefore intended to be embraced therein.
